PAPER BAG.

SPECIFICATION forming part of Letters Patent No. 234,837, dated November 23, 1880.

Application filed April 2, 1880.

T 0 all whom it may concern:

Be it known that I, DANIEL APPEL, of Cleveland, county of Ouyahoga, State of Ohio, have invented an Improvement in the Mannof which the following description, in connection with the accompanying drawings, is a specification.

This invention relates to improvements in the art or method of manufacturing paper bags, as will be hereinafter set forth and particularly claimed.

In this my invention the web of paper, led from a suitable reel, is folded transversely and turned back on itself for a short distance from that end of the web from which the bottom of the bag is to be made,- then the web is severed transversely into a bag-length, and a portion of the leading end of the paper so turned back equal in width to the width of the bag to be made is then folded over or forward in an opposite direction upon the portion first folded over, the paste is applied, the web is folded at two points longitudinally, and its past-ed longitudinal edges and bottom-forming parts are brought together or lapped to form a tubular portion and close the bottom. After this, if desired, one part or ply of the leading end of the bag so formed may be turned backward or over upon the body of the bag-tube, while the other portion is held down, thus shaping the bag-bottom as in the drawings accompanying this application. The bag may be pasted together longitudinally, either along one edge or at or near its central part, as herein described, without departing from my invention.

Figure 1 represents, on a reduced scale, a piece of paper sufficiently long and wide to form one bag, it being marked by dotted lines 1 1 2 2 3 3 4 4 at the points where it is to be folded. Fig. 2 represents the same folded back on the line 1 1 and again on the line 2 2. Fig. 3 represents a section of the bag on the line w m, Fig. 2, after the piece of paper, Fig.

2, has been folded on the line 3 3, the paper being represented as somewhat separated in order to avoid confusion of lines in the draw ings, it being understood, however, that the paper in the form represented in Fig. 3 is closely held together at its side and one end to form a tight bag-bottom. Fig. 4is a longi- (No model.)

tudinal section of Fig. 2. Fig. 5 represents a top view of the way in which one end of the double end of the bag may be laid back on the body of the bag, if desired. Fig. 6 represents a piece of paper with one end bent back on the line 1 1, as shown in Fig. 1; but in this, Fig. 6, it will be noticed that the piece to be folded in the opposite direction and pasted to the portion first folded over is only of the width of the folded bag, or one plyof it, and is turned over forward from the central part of the width of the web of paper rather than from one side,

the lines 3 y z 'z in the said figure indicating the points of longitudinal folding, the paper so folded lapping its edges near the central part of the bag.

The piece of paper A will be supposed to be part of a web of paper connected with a roll until after it is folded for the first time on the liuel 1, when sufficient paper for a bag-length is severed from the said web. The paper for its whole width is folded transversely on the line 1 1, and turned back on the main body of the paper, after which that portion of the paper so folded back is for substantially half its length, or for a distance equal to the width of the completed bag, folded in the opposite direction or forward on the line 2 2, leaving a lip, 1), extended half-way, or nearly so, across the web or paper. The paper is then pasted, as shown by the cross-lines 10, on one-half only of the portion folded back from the line 1 1. This lip b, corresponding in width with the width of the bag, may be turned back either at one side of the paper, as in Figs. 1, 2, or intermediate between the edges 5 6 of the paper, as in the modified form, Fig. 6, to be referred to hereinafter. The paper is then folded longitudinally on the line 3 3, after which the edge 5, having been pasted, is lapped over upon the edge 6 of the paper, the fold being made on line 4 4, the pasted portion thus adhering to the lip b, completing the junction of the paper to form a closed bag.

In casethe longitudinal lap of the bag is to be made at or nearits center, as in Fig. 6, then the lip b will be formed near the center of the paper for a length equal to the width of the bag to be made, so that the paper folded on the lines 3 y z 2 will cause the face of the lip 11 to adhere to the paste, (shown by crosslines 12,) the pasted side edges of the paper thus also overlapped completing the closing of the bag.

In each of the bags so far described the bottom-forming part will, at its extreme end, appear as in Fig. 4; and should it be desired to make the said bottom appear as in Fig. 5 itis only necessary to keep down the portion d and turn back the portion 6, when the bag-bottom will appear as in Fig. 5. In another application, which I expect very soon to file for United States patent, I shall describe a machine for performing this work automatically. In it the folds 1 1 will be formed with a tucking-blade and rollers as will the longitudinal folds.

In the several figures the series of parallel dashes represent lines of paste, which may be applied by means of suitable rollers or otherwise in any usual manner.

I am aware that a bag has been made by turning the end of 'the web back on itself transversely along the line 1 1 for its whole width, and that the entireportion so turned back has then been folded forward on a line intermediate between the line of fold 1 and the end of the web previously turned back, as in United States Patent No.1'55,611; but such folding makes a clumsy bottom and requires more pasting than by this my method.

I claim- That improvement in the art or method of making paper bags which consists in folding the bottom-forming end of the web or paper back upon itself on the line 1 1 for the width of the web, then folding the same part for substantially one-half the width of the web forward in the opposite direction to form a lip, b, as wide only as the bag to be made, then pastinga part of that portion of the end of the web turned back on the line 1 1, pasting one of the longitudinal edges of the web or piece of paper to form the bag. and then folding the said piece of paper longitudinally at two points, as described, to thus lap its side edges and complete the closing together of the paper at one end to form a bag with a closed bottom, all as shown and described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

DANIEL APPEL.
